If you are using JSP, the view handler dispatches to the target JSP. The dispatch is a forward that invokes the JSP building the component tree while rendering the document. This logic is in the renderView method of the view handler [2]. externalContext.dispatch(viewId); I don't think you will be able to store the content of the view in a DB if you are using JSP but you might be able to do this using an alternative. With a few modifications, Shale Clay [1] would allow you do store templates in a database. You could store the content as markup fragments or maybe in database tables. I've played with this idea but have not found the interest to take it to the next level. There is a project in the shale sandbox that uses JPA to store metadata that could be used to construct the component tree [3]. This method would be like maintaining an XML file [4] in a DB. Or, maybe the better approach would be to store markup fragments in a DB or better yet a Jackrabbit repository? Clay has a couple parsers that are snapped in to read different types of markup [5].
